Yam is also what we usually call Huaishan. Do you know how to plant it? Yam is a kind of warm-growing crop. The suitable temperature for rooting and germination is about ten to twenty-four degrees. In most of the provinces and cities except for some particularly cold areas, yam can be grown.
First, planting points
Soil selection
The yam planting soil is recommended to choose soft sand, areas with high topography and drainage, and the soil pH value is preferably slightly acidic or neutral.
2. Trenching
Generally, the length of the ditches is determined according to the type of yam. After digging the ditch, it is not necessary to plant the seeds immediately. Generally, it is necessary to dry the air for several days according to the temperature, and then backfill the soil ditch, and backfill according to the bottom layer, the lower layer and the middle layer. The order of the soil is compacted and the surface is finally cleaned up.
3. Variety selection
The selection of the variety should be determined according to local climatic conditions and other factors, and then the dental block with high pests and high vigor should be selected as the seed, and the incision should be sterilized with ash and then planted.
Second, field management
Bracket
The growth of yam must keep the vines away from the ground. The yam vine just grows out and is pulled by the bracket, letting its vines climb up slowly. Common low-cost brackets are constructed of bamboo blocks, with a herringbone frame or frame frame, with a height of about 2m.
2. Weeding
When the yam stems are wound onto the scaffold, weeding is carried out once every two months. When weeding, part of the soil between the frames is dug into the frame, causing the frame to bulge. The outside of the frame is formed to a depth of 20cm and a width of about 30cm, which is favorable for drainage in the rainy season.
3. Fertilization
When the vine is rolled into the half of the stent, a fertilizer can be applied. Generally, urea is used, and the amount of fertilization is measured according to the growth condition and the color of the vine leaves. There are few strong applications, and weak seedlings are applied. Even if the vines are full of the entire stent, it is found that there are weak seedlings or yellow leaves that can be fertilized again.
4. Irrigation and drainage
Yam is very resistant to drought. If you want high yield, you should pay attention to the measurement of watering. Generally speaking, before and after the first top dressing, if the soil is dry, you can water it a little or two times. In the rainy season, drain the ditch and drain in time to avoid water accumulation in the field.
The above is the cultivation point of yam. We welcome more experienced farmers to continue to supplement. What kind of knowledge do you want to learn about yam?
